Image Thumbnail on Report - Public Image URL

We've identified a solution for this and were able to achieve what we set out to do:

displayname=Asset Preview
image.name=Asset Preview (click for full size)
image.valuefield=DE:SGWS | Front label image
link.isnewwindow=true
link.url=DE:SGWS | Front label image
textmode=true
type=image
valuefield=Asset Preview URL
valueformat=

Becker,

Something like the below?  For the below I setup conditional formatting to show a green dot first when the field wasn't empty.  I then went into textmode and changed the url of the green dot to be the URL you had above, seems to work.
